If your already planning on replacing the chassis and having the firearm cerakoted etc I wonder if you have thought about using a cheaper savage as a base for your build. You could get hold of one of the cheaper Savage models with a model 10 short action.
You may need to add an after market trigger such as Timney, if you choose a model without the accu trigger. You could then budget for a prefit after market barrel with the specs you want. Pre fits are easy to install and have a high degree of probability that they will shoot.
The reason I am mentioning this is because although I seem to like Savages, I have owned 3 short and 2 long action based models, at the end of the day they are a factory barrel. Some will shoot to your requirements and some will not.
You could possibly put together something a similar, with an after market barrel for not too many more dollars and a little more work. Having said that I think you already got a good project going and it may take time to source a prefit. I am sure you will have fun whatever.
